Can rollers be adjusted instead of replaced?
Sometimes a quarter-turn is all it takes. Other times adjustment just delays the inevitable. Here's how to tell which you're dealing with.

How roller adjustment works
Most sliding panels have a small adjustment screw hidden at each bottom corner, behind a plug or in the face of the stile. Turning it raises or lowers that corner of the panel on its roller. This corrects a door that scrapes or sits crooked — when the rollers themselves are fine.
When adjustment is enough
- The door recently started scraping but the wheels still spin freely.
- The panel sits slightly crooked with an uneven top gap.
- The door was serviced or moved and just needs re-leveling.
When it won't hold
If the wheels are corroded, flat-spotted, or seized, no amount of adjustment restores a smooth roll — you're just changing the height of a bad wheel. It might feel better for a week, then return. At that point replacement is the real fix.
Trying it yourself
You can try the adjustment screws with a screwdriver — a small turn at a time, testing as you go. If it doesn't give you a smooth glide, stop before you force anything and consider roller replacement. Don't pry the panel out yourself; the glass is heavy.
